RE: Low power Distance Sensor - Hardware issues
@qqlapraline Just use a 5V pro mini and get rid of level converter and mosfet!
Power the 5V HC-SR04 sonar with a pro mini digital pin.
Switch on the sonar for doing a measurement and then switch off again and put the promini to sleep till the next measurement.
